US Airways will fly its last flight Friday as its merger with American Airlines is completed.

US Airways Flight 1939, named for the year the airline was created, will fly round trip from Philadelphia to San Francisco with stopovers in Charlotte and Phoenix.

The history

What is today US Airways is a long history of mergers and name changes that leads up to the modern day American Airlines.

In 1948, Piedmont Airlines began operations in Charlotte. The regional operator carried passengers, air mail, and other freight across portions of Ohio, Virginia and the Carolinas. By 1968, Piedmont Airlines would merge with Empire Airlines, which would merge into the USAir family two years later.

By 1989, USAir was a 50 year old conglomeration of airlines. Its history is traced back to All American Aviation, born in Pittsburgh in 1939 as a Northeast operator. By 1953, All American Airways changed its name to Allegheny Airlines before eventually becoming USAir in 1979. By that time, the airline was looking to expand its service to other parts of the country. By 1989, it would acquire Empire Airlines and its subsidiary, Piedmont Airlines, as a way to expand into the Southeast and other regions. In that same year, the newly combined airlines would make Charlotte one of its regional hubs.

In Charlotte

By 1990, USAir had its own hanger and maintenance facility in Charlotte. In 1997, USAir would become US Airways, which a year later purchased a number of regional operators. By 2002, the US Airways Express regional operator had a new 95,000 square foot facility in Charlotte. US Airways Express is now the division that operates the remnants of the earlier Piedmont Airlines brand.

The American Airlines group of companies account for 91 percent of the 44.3 million people who traveled through Charlotte Douglas International Airport in 2014, according to the airport. The airline group employees 11,110 people in the Charlotte area. American operates 770 daily departures from nine cities in North Carolina, providing access to more than 338 destinations around the world.
